什么是四氯化碳？

四氯化碳是具有化学式CCL的化合物₄. It is commonly called “tetrachloromethane”. Carbon tetrachloride is a colourless liquid having a sweet smell. Therefore, it is easy to detect this compound from its smell even at low levels.

The molar mass of carbon tetrachloride is 153.81 g/mol. It has a melting point of −22.92 °C, and the boiling point is 76.72 °C. When considering the geometry of the carbon tetrachloride molecule, it has the tetrahedral geometry. There are four chlorine atoms bonded to a single carbon atom, and the bond angles of the molecules are equal. Therefore, we call it a “symmetrical geometry”. This geometry makes the compoundnonpolar. It resembles the structure of a methane molecule, which has four hydrogen atoms bonded to a single carbon atom.

There are many uses of carbon tetrachloride. Before the prohibition, this compound was used to produceCFCin large scale. Nowadays, we do not produce CFC since it harms the ozone layer. Carbon tetrachloride is the key ingredient in lava lamps. Once it was a popular solvent, but now we don’t use it due to its adverse health effects. Moreover, we widely use it in fire extinguishers, as a precursor to refrigerants and as a cleaning agent.

What is Sodium Chloride?

Sodium chloride is an inorganic compound having the chemical formula NaCl. The molar mass of this compound is 58.44 g/mol. At room temperature and pressure, sodium chloride appears in solid-state, as colourless crystals. Moreover, this substance is odourless. In its pure form, sodium chloride cannot absorb water vapour, which means, it is not hygroscopic.

氯化钠是钠的盐，因此它是一种离子化合物。该化合物每个分子的每个钠原子都包含一个骗子原子。氯化钠盐负责海水的盐度。熔点为801°C，而沸点为1413°C。在氯化钠晶体中，每种钠阳离子都被六个氯离子包围，反之亦然。因此，我们将晶体系统称为面部为中心的立方系统。

Sodium chloride dissolves in high polar compounds such as water. Here, water molecules surround each cation and anion. Each ion often has six water molecules around them. However, the pH of an aqueous sodium chloride lies around pH7 due to the weak basicity of chloride ion. We say there is no effect of sodium chloride on the pH of a solution.

What is the Difference Between Carbon Tetrachloride and Sodium Chloride?

Both carbon tetrachloride and sodium chloride are chlorine-containing chemical compounds. The key difference between carbon tetrachloride and sodium chloride is that carbon tetrachloride is a covalent chemical compound whereas sodium chloride is an ionic chemical compound. Moreover, carbon tetrachloride dissolves in nonpolar solvents while sodium chloride dissolves in polar solvents.

Below infograhic summarizes the differences between carbon tetrachloride and sodium chloride in tabular form.

摘要 - 四氯化碳与氯化钠
